RAPID-MIXING FLAsK il `Applicationl led'March 15, 1926.-l `Serial` N0.94,764.

This invention relates to flasks for mix-v ing liquids.

The ob]ects of the invention are, first, to provide separate containers, each-of which a is adapted to receive and hold a distinctV liquid therein, each of said containers being adapted to stand alone on its own base; second, to shape the necks of said containers whereby the orifice of one may be inserted lo into the orifice of the other; third, toshape the bulbs of the containers whereby, when the vessels are tipped with their necks in alinement in a horizontal line and one is inserted in the other, the liquids may still be held in their respective bulbs and `out of contact with each other and, whereby, when the bulbs are turned to extend upward into mixing position, the necks of the two containers form a continuous straight and smooth passage between the lowest pointsof each of the two bulbs, thereby permitting the rapid and complete mixing of the liquids by surging the combined liquids from end to end of the passage.

I attain these and other objects by the devices, forms and shapes illustrated in the accompanying drawings, in which- Figs. 1 and 2 are side elevations of the two flasks, in position for receiving Athe :w respective liquids; Fig. 3 is an elevation of the vessel formed by the two fiasks when tipped and connected together, the liquids therein being still held in the respective flasks; and Fig. 4 is a vertical section of the flasks forming the mixing vessel when turned into mixing position.

Similar numerals of reference refer to similar parts throughout the several views.

In many of the arts and professions it is necessary to mix liquids suddenly and rapidly in order to` attain the desired quality or kind of mixture between the several liquids. for instance, in biological laboratories this is necessary inV order to obtain an unstable colloidal mixture such as is necessary to per form the required tests.

Referring to the drawings it will be seen that I provide two similar flasks 1 and 2, each of which is provided with a bulb or containing chamber 3, having a flat bottom 4, on which it may be independently stood, and a neck 5 whichis o'setfrom the usual position and is arrangedso that its lowest line, when the flask is turned down as in Fig. 4, is in alinement with the lowest line of the bulb or body of the flask. The orifice (3 of the neck 5 of the flask 1 is slightly enlarged and its inner surface is ground to an accurate conical shape. The outer surface of the end 7 of the neck 5 of the flask 2 is reduced and ground to fit tightly in the above mentioned orifice G. The two necks 5 therefore form a continuous passage which, if the flasks are `which the liquids in the said bulbs 3 have been emptied and in which they may be violently `or rapidly shaken or surged to thoroughly and completely mix them and to produce the desired quality of mixture or suspension of the substances inthe combined liquid.

My `improved flasks are used in the following manner Flasks 1 and 2 are first stood on their fiat bottoms 4 (Figs. 1 and Q) and the measured quantities of the several liquids are placed therein, one liquid in each; they are then turned with their necks away from each other, as in Figs. 1 and 2; they are then held in the two hands of the operator and are tipped in opposite directions to bringr their necks 5 in line with each other, the bulbs 3 being lower` than the said flask 2 is inserted into the orifice 6 of the y flask 1; and then thecombined vessel, thus formed, is turned on the longitudinal axis of the necks 5 to bring the bulbs 3 above the level of the said necks and to cause the two liquids to fall therefrom into the passage or vessel formed by the necks, and the sides of ill) the bulbs 3, and then, at once, the combined vesselis agitated horizontally tocause the thev passage and to thus become rapidly mixed.

Thus it will be seen `that I have provided a pair of flasks in which the bulbs are each o'set from the neck and extend to one side thereof so that, when the bulb portion of the flask is turned upward and the neck thereof is held horizontally, no portion of the bulb will lie below the line of the lower portion of the neck.

Having therefore described my invention, what I claim is 1. A device of the character described comprising a pair of similar complementary flasks, each adapted to receive a differentand a neck portion, the neck of one flask beliquid, each flask comprisinga bulb portion ing adapted to enter and it in the neck of the other flask, whereby the two necks form asingle continuous mixing passage, each bulb *being oset from the neck and extending to one side thereof whereby7 when the necks are in closed connection with each other and the bulbs are turned downward, the several liquids are held therein and whereby, when the vessel thus formed is rotaed to bring the two bulbs upward, the liquids are emptied into jhe mixing passage formed by the necks and may be agitatedV and mixed therein.

2. A device as set forth in claiml, wherein each bulb has a flat botron'i whereon it may Stand when the neek thereof is iu vertical position.
